Low-energy-consumption carbon-enriched electric energy cement clinker firing system
The invention discloses a low-energy-consumption carbon-enriched electric energy firing cement clinker production system, and belongs to the technical field of cement production. Comprising a cooling machine, a rotary kiln, a smoke chamber, a plasma furnace, an ionization gun, a rotational flow chamber, a decomposing furnace, a first raw material preheating and pre-decomposing system, a second raw material preheating and pre-decomposing system, a smoke circulating system, a high-temperature fan, a waste heat power generation system, a tail exhaust fan and a kiln tail dust collector. A first draught fan, a second draught fan, a third draught fan, an air heat exchanger, a dust collector and a CO2 capturing system are sequentially arranged on an air pipe of an air outlet of the uppermost-stage cyclone separator of the flue gas circulating system, a discharging pipe of the lowermost-stage cyclone separator of the flue gas circulating system is connected with a flue gas chamber, and the flue gas chamber is not directly communicated with the decomposing furnace. And the smoke chamber, the rotary kiln and the cooling machine are connected in sequence. The problems that in the cement clinker production process, the CO2 enrichment concentration is low, and the plasma torch combustion temperature is unstable are solved, CO2 in flue gas is captured and purified, and heat loss of a system is effectively recycled.
本发明公开了一种低能耗碳富集的电能烧成水泥熟料生产系统，属于水泥生产技术领域，包括冷却机、回转窑、烟室、电浆炉、电离枪、旋流室、分解炉、第一生料预热预分解系统、第二生料预热预分解系统、烟气循环系统、高温风机、余热发电系统、尾排风机、窑尾收尘器；所述烟气循环系统的最上一级旋风分离器出风口风管上依次设有第一风机、第二风机、第三风机、空气换热器、收尘器和CO2捕集系统，所述烟气循环系统的最下一级旋风分离器下料管与烟室连接，所述烟室与分解炉不直接相通，所述烟室、回转窑和冷却机依次相连。解决水泥熟料生产过程中CO2富集浓度低、等离子火炬燃烧温度不稳定的问题，实现烟气中CO2的捕集提纯、有效回收利用系统热损失。
